When you use the grid, place a piece of unlined blank paper (or tracing paper)
over it and use a pencil to sketch on the tracing paper, following
the lines of the grid. If you draw on blank paper or tracing paper,
you can remove the grid from beneath your drawing and the
drawing will look much nicer than if you draw directly on the grid.
Begin with simple shapes and then combine shapes to form more complex
drawings.
